I love the Seattle Aquarium. They have multiple otter exhibits as well as interpretive guides to the Puget Sound. I also adore puffins and the northern fur seal. But the otters win for cuteness! There are a wide variety of tropical and local fish to stare at. The pacific octopus is a winner and has even caused an uproar when they placed him in a tank with sharks and the sharks got the shit end of the deal. My video has a bit of them all but of course extra otter photos.
